Vortex 245/254 Street Reaper — LS 3-Bolt Hydraulic Roller Camshaft SMALLER BACE CIRCLE
The Vortex 245/254 Street Reaper is built for LS engines that demand maximum top-end power, aggressive idle, and brutal exhaust pull through the upper RPM range.
With a split-duration design of 245° intake / 254° exhaust @ .050", the Street Reaper is engineered to dominate high-RPM airflow and exhaust scavenging, making it ideal for engines with ported heads, long-tube headers, and high-flow intake systems. The extended exhaust duration allows the engine to stay efficient at high RPM, delivering a hard, relentless pull past the midrange into the upper powerband.
This is a serious camshaft with a deep, violent chop at idle and race-driven power characteristics, built for aggressive street/strip combinations and high-performance LS builds.
Designed for any Gen III / IV LS 3-bolt engine, the Street Reaper transforms LS setups into high-revving, hard-charging combinations that don’t fall off up top.
